Answer:
C
Step-by-step explanation:
We need common denominator, which in this case is 40.
6*5 is 30 and 4*8 is 32.
We add these up 62/40
Now add the wholes, 5+4 is 9
We have an improper fraction, which will add 1 to 9, causing the answer to be C.
ok but what's the question? u gave us info but what's the question
Answer:
If David were summarizing the data from his sample, he would use Descriptive statistics. If he wanted to know whether or not his sample results could be generalized to the population, he would use Hypothesis testing statistics.
Step-by-step explanation:
Hello!
There are two types of statistics.
1. Descriptive statistics.
This method allows you to summarize the observed data of a sample, it gives you an idea of the data distribution shape, its variability, most common values, etc... You can summarize the data using numerical measures (for example: mean, median, mode, variance) or graphics (for example histogram, scatterplots, boxplots)
2. Hypothesis testing.
Using this method you can test the results of an experiment, using the previously summarized sample data, and reach a valid conclusion over your claims that can be generalized to the population of study afterward.
I hope it helps!
There is rotational symmetry if there is a center around the object that is turned or rotated a certain amount of degrees and the shape isn't changed.
If I round 2,420
to the nearest ten thousand. Yet this number is lacking a digit or rather is
incomplete.
Assuming that we
add three zeros to the digit number thus becomes, 2,420,000 and we want to
round it off to the nearest ten thousand it will be 2,420,000 the same digit.
But if we add only
one zero to complete the digit, 24,200 the number becomes 20,000.
